When this movie was announced, something was expected to crush The Little Mermaid (2023), but the result is actually not what was expected. It was already easy to deduce that this would be a simple film, but Chelsea's design made audiences and DreamWorks alike cry victory too soon. In the end, the audience is the one that was wrong to place high hopes in this film. The acceptance of the public was good in part, but the box office rightly says otherwise. This is a movie that tries to use the formula of Shrek spoofing The Little Mermaid, but watching the movie and looking at the script, it's clear that they made it by focusing solely on competing with Disney rather than on making a great-caliber movie. The animation and visual quality of the movie are good with a rather striking colorful look. The character design is mostly questionable. Ruby and Chelsea are the only ones who steal much of the movie and have quite a bit of personality, although like the other characters, they lack further development. Ruby's parents do little and only her mother and grandmother show a little interest. Ruby's friends and love interest are nothing more than filler characters. The jokes are mostly forced, as is the comedy, resulting in few laughs. The concept of the film shows some potential to be a Shrek-style parody, but it's not fully exploited, as it feels like it still had more to offer. Introducing a mermaid as an antagonist is a return to the dark background of mermaid mythology, as mermaids were initially not friendly beings. Turning the Krakens into friendly beings is a twist that gives the film a certain freshness. Even though Ruby has a decent design, it is unlikely that her normal appearance is her human appearance and that no one would suspect that she is a Kraken. That generates a kind of contradictory conflict with the atmosphere of the film. The plot is simple and even predictable, mostly with its plot being in the style of a teen movie. It has some good sequences like the final battle, but it feels like there were still more scenes to incorporate and more development to add. Ruby Gillman, Teenage Kraken is somewhat entertaining to enjoy in family, but it is a very simple and forgettable movie. That makes everyone who godified this movie, without seeing it first and using it to make fun of Disney, nothing more than brainless naives who just wasted their time acting like children. The reality is that this movie did not deserve to be a success because it is inferior to The Little Mermaid (2023) and anyone who says otherwise lacks true cinematographic knowledge. My final rating for this movie is 6/10.
